iPhone or iPad Update to iOS 10?

iOS 10 is here now and will land on all of Apple’s phones and tablets on Tuesday evening, along with a host of new features that might make even old phones feel new. Well, here comes the question: should your iPhone or iPad update to iOS 10?
Instead of offering you a definitive answer to this question, the passage will offer you a general guide before you update iPhone or iPad to iOS 10.
iOS 10 Features
What features will iOS 10 take on?
Learned from Apple’s official website, iOS is better and better, especially with iOS 10. Why? Reasons are as follows:
#1 iMessage will allow you to express yourself in a much bolder new way. 
  • Write it yourself. Send a message in your own handwriting. Your friends will see it animate, just as ink flows on paper.
  • It’s how you say it. Change the way your message bubbles look. Say it proud. Say it loud. Or whisper it.
  • Let’s celebrate. Say things like “Happy Birthday!” or “Congratulations!” with animations that take over the entire screen.
  • Invisible ink. Send a message or photo that remains hidden, then simply swipe to reveal it.
  • Tapback. Just tap to send one of six quick responses that let people know what you’re thinking.
  • Add a personal touch. Send fireballs, heartbeats, sketches, and more. You can even draw over videos.
  • Stickers. Slap them on top of bubbles, dress up a photo, or even put one on another sticker. Available in the new App Store for iMessage.
  • Tap to replace emoji. Swap out words with emoji — all with a simple touch. That’s something to  :-) smile about.
  • iMessage apps. Easily access your favorite apps to create and share content, make payments, and more, without leaving Messages.

#2 Find your route with beautifully redesigned Maps.
  • Now taking reservations. Book a table through apps like OpenTable, and a ride with Uber — all within Maps.
  • Street smarter. Maps can make proactive suggestions for where you’re likely to go and the fastest way to get there.
  • Search along your route. See what’s around the corner and easily find the closest places for gas, food, or coffee. Maps even tells you how much extra time it will take to arrive.

#3 Use the power of Siri in more apps than ever.
  • Siri. Now open to apps. Siri works with your favorite apps from the App Store, so you can ask it to book a ride through Lyft, or send money to someone with Square.

#4 Relive memories like never before in Photos.
  • Your past, beautifully presented. The photos app can help you rediscover cherished memories – like a weekend hike or your baby’s first birthday – and even create beautiful movies out of them.

#5 Other more favorite features are still smashing enough.
  • Home smart home. The new Home app lets you turn on lights, unlock doors, and even raise your window shades — all at once if you like.
  • Music. Redesigned. The simple, intuitive design makes it even easier to enjoy your favorite songs. You can also view the lyrics while you’re listening to them.
  • Raise to wake. Simply pick up your iPhone to wake it up. Your notifications will be there waiting for you.
  • Touch and go. Use 3D Touch in apps like Calendar, Weather, and Stocks for a quick glance at the information you need.
  • Rich notifications. View photos and videos or respond to a message right in your notifications.
  • Contextual predictions. Typing is quicker and easier than ever. When you type something like “I’m available at,” the free time in your calendar pops up as an option.
  • Your news never looked so good. Easily find the stories that matter to you most, in distinct sections of the beautifully redesigned News app.
  • Been there. Found that. Search your photos by the people or things in them, like a beach, a football game, or a puppy.
  • Multilingual typing. Now you can type in two languages at the same time without having to switch between keyboards.
  • Apple Pay on the web. Shopping online is now faster, safer, and more private than ever. Just browse, then pay in your browser.

Rumors on iOS 10 downsides?
#1 Will you have enough storage space to update to iOS 10 on iPhone, iPod Touch, and iPad?
Very likely! Since last year, Apple has been working hard to make iOS updates smaller and easier to download and install. Well, iOS 10 beta update shows 1.7GB size and would require about 1.5GB of temporal space in order to completely install the new operating system iOS 10. 
Hence, you are expected to have at least 4GB of storage space before updating. If you do have limited space and have no idea to delete some apps, mophie space pack is something optimal to the solutions. Learn more: mophie.com/shop/space-pack

#2 Excessive battery drain when updated and used normally?
Since the iOS 10 bata 7 is released, as well as other version before it, have caused excessive battery drain for some people, even when the iOS device is being used normally.  Well, I wanna say, the battery drain varies depending on your usage patterns. 
If you crank up the brightness all the way up, chances are iOS will recommend either reducing brightness manually or using the Auto-Brightness function.
Similarly, if someone uses mostly cellular data and does a lot of web surfing on their device, they might see a suggestion to disable cellular data, and so forth.
Many average users are unaware that using cellular data consumes power faster or that the biggest power draw in a mobile device with an LCD display is the screen itself.
You could head to Settings > Battery to check what apps consume most of your battery.
